<span>As only one team is to be made that means we have to choose 2 people from total 13 people. As the order that two people are selected does not matter here so we just have to make all possible combination of the team So the answer is 13*12/2 answer= 78 ways</span>

Answer:

The value of an appropriate test statistic for the car dealer to use is -4.

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 4600$

The alternate hypotesis is:

$H_{1} < 4600$

The test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation and n is the size of the sample.

In this problem:

$X = 4100, \mu = 4600, \sigma = 500, n = 16$

Then

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$t = \frac{4100 - 4600}{\frac{500}{\sqrt{16}}}$

$t = -4$

The value of an appropriate test statistic for the car dealer to use is -4.
